This invention relates to rims which are used
for mounting. the tires of motor vehicles upon
for retreading in a vulcanizing mold.
The invention has been specially devised to pro
and 5, each having a side rim ?ange 6 and a well
?ange respectively numbered 1 and 8, the said
well ?ange 1' being adapted to overlap its fellow
8 and to slide thereupon as the rim parts 4 and
5 are advanced together or retired apart. The
well ?ange 8 (Fig. 3) is formed to provide an an
4 O nular shoulder 8a on the upper surface thereof.
This ?ange 8a. supports one bead of the tire to
maintain the bead at the same height as the bead
supported upon the ?ange l and prevents said
?rst bead from being pinched between the free
45 edge of the ?ange ‘l and the rim ?ange 6 of the
member 5 when the members 4 and 5 are moved
together. The rim ?ange 6 and the junction
with the Well ?anges may be contoured or shaped
inwardly according to the bead or edging of the
50 tires to be treated. ,
Each of the rim parts 4 and 5 has a side frame
formed of two side bars 9 a?lxed by welding or
other suitable means across the outside edgein
